Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17646, here are decompositions:

19 + 17627 = 17646
23 + 17623 = 17646
37 + 17609 = 17646
47 + 17599 = 17646
67 + 17579 = 17646
73 + 17573 = 17646
107 + 17539 = 17646
127 + 17519 = 17646

Showing the first eight; more decompositions exist.
